How does Brother Yun use imagery in The Heavenly Man: The Remarkable True Story of Chinese Christian Brother Yun?

Imagery:

'In China I had been used to beatings, torture with electric batons, and all kinds of humiliation. I guess that deep in my heart I had presumed that now I was in the West my days of persecution had ended."

"Don't pray for the persecution to stop. We shouldn't pray for a lighter load to carry, but a stronger back to endure."

"When God starts to move, the best we can hope to do is go along for the ride. All man-made plans and strategies become futile and worthless, and are swept away like an umbrella in a mighty hurricane."
